21697875 ÷ 493 
We're looking to find how many times 493 goes into 21697875.

Let's proceed to step 1:
When dividing 2 by 493, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 493

Advancing to step 2:
The number 493 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 493

On to step 3:
493 can be fit into 216 0 times, resulting in a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Grab the next digit (9) from the dividend, add it to 216, then carry on: 2169 / 493

Moving on to step 4:
493 goes into 2169 4 times with a remainder of 197.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1972 from 2169 and we're left with 197.
Fetch the next digit (7) from the dividend, attach it to 197 and continue: 1977 / 493

Advancing to step 5:
1977 divided by 493 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 1972 from 1977 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 493

Step 6:
The number 493 fits into 58 0 times, leaving a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 440.0
Subtract 0 from 58 to get 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 493

Going ahead to step 7:
493 goes into 587 1 times with a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 4401.0
If we subtract 493 from 587, we get 94.
Take the next digit (5) from the dividend and append it to 94, then repeat: 945 / 493

Let's proceed to step 8:
493 can be fit into 945 1 times, resulting in a remainder of 452.
The next digit of our result is 1. 
Result so far: 44011.0
Deduct 493 from 945 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 9:
493 can be fit into 4520 9 times, resulting in a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 44011.9
Subtracting 4437 from 4520 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 10:
When dividing 830 by 493, we get 1 with a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 44011.91
The remainder is 337 after subtracting 493 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 11:
The number 493 fits into 3370 6 times, leaving a remainder of 412.
The next digit of our result is 6. 
Result so far: 44011.916
Deduct 2958 from 3370 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 12:
If we divide 4120 by 493, we get 8 and a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 44011.9168
The remainder is 176 after subtracting 3944 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 13:
The number 493 fits into 1760 3 times, leaving a remainder of 281.
The number 3 becomes the next digit in our result. 
Result so far: 44011.91683
Subtracting 1479 from 1760 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 14:
2810 divided by 493 is 5 with a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 44011.916835
If we subtract 2465 from 2810, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 15:
493 goes into 3450 6 times with a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 44011.9168356
If we take 2958 away from 3450, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 16:
493 goes into 4920 9 times with a remainder of 483.
The number 9 becomes the next digit in our result. 
Result so far: 44011.91683569
Subtract 4437 from 4920 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

After the division, we end up with 44011.91683569 and a remainder of 4.83e-07.
